The M1A SOCOM 16 Compact and powerful, it features a 16-inch barrel made possible by a retuned gas system. It is a heavy-caliber alternative for a CQB (Close Quarters Battle) rifle, as well as the ideal patrol, ranch or pickup rifle. Other features include a black fiberglass stock, forward-mounted scout-style scope mount, and a proprietary muzzle break that virtually eliminates muzzle rise.
